S930 misinterpret class getter as function calls

[fxOne]

I want to report a bug.

SonarJS version: 2.21 (build 4409)
SonarQube version: 6.3.1 (build 21392)

Rule key: javascript:S930

Reproducer

class {
  /**
   * @return {Function}
   */
  get callback() { 
    return this._callbackFn;
  }

  executeCallback(param) {
    this.callback(param);
  }
}

I'm getting the error: "callback" expects 0 arguments, but 1 was provided.

Expected behavior
There shouldn't be any error as the callback getter can return a function.

@fxOne thanks. It's not the rule itself, it looks like our type model associates the getter to a FunctionType because accessors declarations are a special case of function declaration, but upon use they don't behave like functions : invoking this.callback does not return the get callback() {...} function as any other unparenthesized call to a method would, but rather the value returned by get callback() {}.
The type model does not reflect this peculiarity.
